SVG Sparklines - Categorical Columns

Power BI now allows the dynamic creation of Scalable Vector Graphics (SVG) images. Prior to the August 2018 version, it was possible to build SVG content into custom columns, but now it is possible to create measures that dynamically update to account for user selections and filters.

Substitute your own measure in place of[Measure Value], a column for'Table'[Customer Segment]for the categorical X axis, and a column for'Table'[Category]that will appear on the same table row as the sparkline.

Since the x axis is categorical, it is built and sorted using RANKX. Bar Width is found by dividing 100 by the number of distinct categories, and columns are adjusted to the range 0-100 by multiplying Rank * Bar Width.

The y axis is complex because of the need to account for a mix of positive and negative values. If all Y values were positive, the axis could use[Measure Value] / Maxand would be fairly simple. Instead, depending on the combination of positive only, negative only, and mixing negative and positive values, there are SWITCH( ) statements used for establishing both the SVG Y value and the Height of the bar.

CONCATENATEX combines the separate SVG rectangles.

IF(HASONEVALUE('Table'[Category])[...]helps hides the total in a Table or Matrix because the total renders as text and not an image.

Once the sparkline measure is ready, set the Data Category to Image URLand add the sparkline measure to a Table or Matrix visual.

In addition, change the BarColor variable from static to dynamic to create conditional color formatting. In this example, if the Margin % is not greater than 20%, the sparkline should be grey instead of green. Because Firefox will not render # in SVG, substitute %23 in place of # if using hex colors.

Re: SVG Sparklines - Categorical Columns

Question: One thing that's not clear to me is whether the images these use have to sit in a square container in the grid. In the case above, if there were say 8 more series, meaning twelve columns in all, is it possible to have the resulting SVG -generated sparkline sitting in a rectangular grid instead of a square grid, so that the spacing between rows is exactly as it is in the file, while leaving the image at the same size as it currently is? i.e. like this:

Re: SVG Sparklines - Categorical Columns

Hello, I have noticed that if I filter the table to show only one record using a slicer visual, the graphic errors and I lose all other information within the table. Is there a way around this? It works well otherwise. On a separate note, would it be possible to show an example of using a pie chart instead of a bar graph?
